Second-order elastic-plastic stability analysis of steel semi-rigid frame

SU Jingling,LI Xiumei,QIN Rong(College of Civil and Architecture Engineering,Guangxi University,Nanning 530004,China)  
The mechanical properties of semi-rigid connection were simulated by rotational spring and Kish-Chen three-parameter model.A common semi-rigid beam element model with zero-length rotational spring at both ends of the beam was used.Based on the beam-column method,considered second-order effect and semi-rigid connection,the element stiffness equation and matrix were derived by differential equations and stability function.According to modified Newton-Raphson iteration method,the calculation format of steel frames second-order elastic stability analysis was constituted.Finally,through the analysis of a typical steel frame,the impact of semirigid connection and second-order effect on the stability were showed.
